Auxiliary Y-Direction Path for Article Sorting Facility Congestion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing article sorting facilities with multiple transport vehicles experience efficiency decreases due to congestion at intersections, where only one vehicle can pass at a time, leading to waiting vehicles and reduced transport efficiency.
Innovation Solution
The article sorting facility incorporates an auxiliary Y-direction path in the connection area, allowing some transport vehicles to divert onto this path, reducing the number on main Y-direction paths and creating standby positions to alleviate congestion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If multiple transport vehicles travel on the same path to improve resource utilization, then device complexity is reduced, but congestion occurs at intersections causing transport efficiency to decrease
Solution Approach 1:
The connection area is segmented into multiple Y-direction paths and X-direction paths, creating a grid-like structure. This segmentation allows transport vehicles to be distributed across multiple paths, reducing congestion on any single path while maintaining efficient resource utilization.
Solution Approach 2:
The patent introduces paths in two directions (Y-direction and X-direction) instead of single-direction paths. This dimensional expansion creates alternative routes for vehicles, allowing them to bypass congestion by switching directions and reducing waiting times at intersections.
2Reliability
If transport vehicles wait at positions likely to cause congestion to maintain safe spacing, then collision risk is reduced, but transport efficiency decreases due to waiting time
Solution Approach 1:
The system performs preliminary routing decisions to assign vehicles to optimal paths before congestion occurs. By pre-planning routes that avoid known congestion points and distributing vehicles across multiple paths in advance, the system reduces waiting time while maintaining safe spacing.
Solution Approach 2:
The path assignment system dynamically adjusts vehicle routing based on real-time congestion conditions. When congestion is detected on certain paths, the system dynamically redirects vehicles to alternative paths, allowing vehicles to maintain safe spacing without excessive waiting time.
3Device complexity
If multiple transport vehicles use the same path to reduce infrastructure, then device complexity is lowered, but the number of vehicles that can travel simultaneously is limited
Solution Approach 1:
The connection area is divided into multiple Y-direction paths and X-direction paths, creating a segmented network structure. This segmentation enables multiple transport vehicles to travel simultaneously on different paths without conflict, increasing the system's vehicle capacity while keeping the infrastructure manageable.
Solution Approach 2:
Each path segment serves multiple functions: Y-direction paths handle north-south traffic, X-direction paths handle east-west traffic, and intersections serve as both through-points and turning points. This multi-functionality allows the same infrastructure to support a higher volume of vehicles traveling in different directions simultaneously.
